Williams was a top-level cryptologist helping to oversee a network called Echelon, which links satellites and super-computers in Britain and the United States with those of other key allies. Set up to monitor the military and diplomatic communications of the Soviet Union during the Cold War, Echelon now eavesdrops on terror suspects and drug dealers, and searches for other political and diplomatic intelligence. It reputedly intercepts five billion conversations and other forms of communications every day. Echelon looks for key words and phrases that might suggest, for example, that a terrorist attack is being planned.
